When a person want to create a game must draw the sprite , or coul take it from some sites or other?I m a novice , i've study a little tutorial , now I want to try something but I'm not able to draw sprite...

Oh, okay. You can just draw some little pictures, right? Not too hard. You could just copy paste stuff too! It doesn't matter. Just draw whatever. You could draw a potato for all it matters. There are sites for pixel art:Pixel JointPixelation

Ok thanks I get start with this : http://www.hongkiat.com/blog/pixel-art-tutorials/ , the first tutorial ... But i've a problem after drawing the cube if I load the file.png , java paint also the background and the tutorial don't explain like avoid this..

Ok, i use paint like tutorial and with difficult i ve found ezimba a site that permit to modify image ... Now ,another problem, i've set the trasparency and all work , but when i put my sprite to y=0 , my sprite not is in the down part of screen but a bit more up , so i think that because , the background is trasparence but exsist and so it is calculate like part of sprite and so don't solve my problem..

It sounds like the image is larger than your sprite. Java doesn't care that the sprite only takes up a (for example) 4x4 area of your 8x8 image. What you need to do is make sure that the actual image is the same size as the sprite. To do this simply crop the image to the size of the sprite. You can google how to crop an image in whatever image editor you're using.

Did I mention paint.net? Paint is just so horrible. I can't even describe how awful an idea it is. You can't import plugins, it's not easy to use, it's a difficult interface... Just an overall bad piece of crap. Just use paint.net.
